TECHNICAL FIELD

The present disclosure relates to the field of optical lens, and more particularly, to a camera optical lens suitable for handheld terminal devices such as smart phones or digital cameras and camera devices such as monitors or PC lenses.

BACKGROUND

With the emergence of smart phones in recent years, the demand for miniature camera lens is increasing day by day, but in general the photosensitive devices of camera lens are nothing more than Charge Coupled Device (CCD) or Complementary Metal-Oxide Semiconductor Sensor (CMOS sensor), and as the progress of the semiconductor manufacturing technology makes the pixel size of the photosensitive devices become smaller, plus the current development trend of electronic products towards better functions and thinner and smaller dimensions, miniature camera lenses with good imaging quality therefore have become a mainstream in the market.

In order to obtain better imaging quality, the lens that is traditionally equipped in mobile phone cameras adopts a three-piece or four-piece lens structure, or five-piece or six piece lens structure. Also, with the development of technology and the increase of the diverse demands of users, and as the pixel area of photosensitive devices is becoming smaller and smaller and the requirement of the system on the imaging quality is improving constantly, a seven-piece lens structure gradually appears in lens designs. Although the common seven-piece lens has good optical performance, its settings on refractive power, lens spacing and lens shape still have some irrationality, which results in that the lens structure cannot achieve a high optical performance while satisfying design requirements for ultra-thin lenses having a big aperture.

DESCRIPTION OF EMBODIMENTS

The present disclosure will hereinafter be described in detail with reference to several exemplary embodiments. To make the technical problems to be solved, technical solutions and beneficial effects of the present disclosure more apparent, the present disclosure is described in further detail together with the figure and the embodiments. It should be understood the specific embodiments described hereby is only to explain the disclosure, not intended to limit the disclosure.

Embodiment 1

Referring to FIG. 1, the present disclosure provides a camera optical lens 10. FIG. 1 shows the camera optical lens 10 according to Embodiment 1 of the present disclosure. The camera optical lens 10 includes 7 lenses. Specifically, the camera optical lens 10 includes, from an object side to an image side, an aperture S1, a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, a sixth lens L6 and a seventh lens L7. An optical element such as a glass plate GF can be arranged between the seventh lens L7 and an image plane Si. The glass plate GF can be a glass cover plate or an optical filter. In other embodiments, the glass plate GF can be arranged at other positions.

In present embodiment, the first lens L1 has a positive refractive power, and has an object side surface being a convex surface and an image object surface being a concave surface; the second lens L2 has a negative refractive power, and has an object side surface being a convex surface and an image object surface being a concave surface; the third lens L3 has a positive refractive power, and has an object side surface being a convex surface and an image object surface being a concave surface; the fourth lens L4 has a negative refractive power, and has an object side surface being a concave surface and an image object surface being a convex surface; the fifth lens L5 has a negative refractive power, and has an object side surface being a convex surface and an image object surface being a concave surface; a sixth lens L6 has a positive refractive power, and has an object side surface being a convex surface and an image object surface being a convex surface; and the seventh lens L7 has a negative refractive power, and has an object side surface being a concave surface and an image object surface being a concave surface.

Here, a focal length of the first lens L1 is defined as f1 in a unit of millimeter (mm), a focal length of the second lens L2 is defined as f2, an abbe number of the first lens L1 is defined as v1, and an abbe number of the second lens L2 is defined as v2. The camera optical lens 10 should satisfy following conditions:

3 0.00≤v1/v2≤4.20;  (1); and

−21.00≤f2/f1≤−5.00  (2).

The condition (1) specifies a ratio of the abbe number v1 of the first lens L1 and the abbe number v2 of the second lens L2. Within such range of the condition, materials and properties can be effectively distributed, thereby improving aberrations while facilitating improving the imaging quality of the camera optical lens 10.

The condition (2) specifies a ratio of the focal length of the first lens L 1 and the focal length of the second lens L2. This leads to the appropriate distribution of the refractive power for the first lens L 1 and the second lens L2, thereby facilitating correction of aberrations of the camera optical lens 10 and thus improving the imaging quality.

In this embodiment, with the above configurations of the lenses including respective lenses having different refractive powers, there are specific relationships between focal lengths and abbe numbers of the first lens L1 and the second lens L2, thereby facilitating correction of aberrations of the camera optical lens. This can achieve a high optical performance while satisfying design requirements for ultra-thin lenses having a big aperture.

In an example, a focal length of the third lens L3 is defined as f3, and a focal length of the sixth lens L6 is defined as f6. The camera optical lens 10 should satisfy a following condition:

3.40≤f3/f6≤8.50  (3).

The condition (3) specifies a ratio of the focal length f3 of the third lens L3 and the focal length f6 of the sixth lens L6. This leads to the appropriate distribution of the refractive power for the third lens L3 and the sixth lens L6, thereby facilitating correction of aberrations of the camera optical lens and thus improving the imaging quality.

In an example, an on-axis thickness of the first lens L1 is defined as d1, an on-axis distance from the image side surface of the first lens L1 to the object side surface of the second lens L2 is defined as d2, and d1 and d2 satisfy a condition of:

4.50≤d1/d2≤9.00  (4).

The condition (4) specifies a ratio of the on-axis thickness of the first lens L1 and the on-axis distance from the image side surface of the first lens L1 to the object side surface of the second lens L2. This can facilitate processing of the first lens and assembly of the camera optical lens 10.

In an example, a curvature radius of the object side surface of the fifth lens L5 is defined as R9 and a curvature radius of the image side surface of the fifth lens L5 is defined as R10, where R9 and R10 satisfy a condition of:

0.40≤(R9+R10)/(R9−R10)≤9.50  (5).

The condition (5) specifies a shape of the fifth lens L5. This can alleviate a deflection degree of light passing through the lens, thereby effectively reducing aberrations of the camera optical lens 10.

In addition, a surface of a lens can be set as an aspherical surface. The aspherical surface can be easily formed into a shape other than the spherical surface, so that more control variables can be obtained to reduce the aberration, thereby reducing the number of lenses and thus effectively reducing a total length of the camera optical lens according to the present disclosure. In an embodiment of the present disclosure, both an object side surface and an image side surface of each lens are aspherical surfaces.

It should be noted that the first lens L1, the second lens L2, the third lens L3, the fourth lens L4, the fifth lens L5, the sixth lens L6 and the seventh lens L7 that constitute the camera optical lens 10 of the present embodiment have the structure and parameter relationships as described above, and therefore, the camera optical lens 10 can reasonably distribute the refractive power, the surface shape, the material, the on-axis thickness and the like of each lens, and thus correct various aberrations. The camera optical lens 10 has Fno≤1.48. A total optical length from an object side surface of the first lens to an image plane of the camera optical lens along an optic axis (TTL) and an image height (IH) of the camera optical lens 10 satisfy a condition of TTL/IH≤1.55. This can achieve a high optical performance while satisfying design requirements for ultra-thin lenses having a big aperture.

In an example, inflexion points and/or arrest points can be arranged on the object side surface and/or image side surface of the lens, so as to satisfy the demand for the high quality imaging. The description below can be referred to for specific implementations.
